Zonnedimmer
Cloud Curtailment

Curtailment at scale

The installed capacity of solar panels is increasing rapidly. This leads to surpluses during sunny periods, or situations where more electricity is fed back locally than the grid is equipped for.

This results in additional costs for PV owners and grid congestion issues, whereas it would be better to temporarily reduce or shut down PV production at these moments.

Zonnedimmer offers market parties and PV owners the ability to perform this curtailment easily and at scale, with:

  • Online activation (onboarding) of PV installations in 2 minutes
  • Support for 90% of the market (8 inverter brands)
  • Contracted grid service integrations with inverter manufacturers
  • Secure Smart Solar API for easy integration
  • Curtailment based on price or control signals from market parties

Key features

Fully Cloud-Based

The Zonnedimmer platform operates entirely via the cloud, with online activation by the PV owner in just 2 minutes.

No modifications to the installation are required, making Zonnedimmer scalable while PV control and monitoring take place as prescribed by the inverter manufacturer, with full support and warranty.

90% Coverage

The brands we support are SolarEdge, Enphase, GoodWe, SMA, Growatt, Solis, Huawei, and Sungrow.

With these brands, our platform provides access to 90% of installed power.

Multi-Level Security

Our SaaS platform is designed with security-by-design at its foundation. For communication between our platform and the cloud environments of supported inverter manufacturers, we use specialized grid services connections with enhanced security features, contracted and under SLA.

Curtailed production estimate

As soon as curtailment takes place, we make an accurate estimate the curtailed production (kWh) per inverter every minute, based on the daily profile and local irradiation data.

This ensures PV owners can be compensated fairly, and agreements can be made on the maximum annual curtailment.

Smart Solar API

With our Smart Solar API, our platform can be easily integrated with existing apps and systems.

PV owners can activate their installation effortlessly and monitor what's happening through your mobile app.

Monitoring portal
